Look at the nar "Hallo", I'm shouting into the mic! Lots of IM.

With a bit of diligence it should be possible to have a nice (clean) signal from an ICOM IC-7300.

Above at Pic 5 my ICOM IC-7300 running 100W just meters away from my ANAN, 7300 connected to a dummy load and below at Pic 6  the IC-7300 connected to my Lazy-D. At Pic 5 we see that the IM3 is down at about 40 dB, and at Pic 6 the beginning of the "blooming" of the signal (Phase Noise) is down by 34 dB.
